Science fiction, abbreviation SF or sci-fi, a form of fiction that deals principally with the impact of actual or imagined science upon society or individuals. The term science fiction was popularized, if not invented, in the 1920s by one of the genre’s principal advocates, the American publisher Hugo Gernsback. The Hugo Awards, given annually since 1953 by the World Science Fiction Society, are named after him. These achievement awards are given to the top SF writers, editors, illustrators, films, and “fanzines.”

The world of science fiction

Science fiction is a modern genre. Though writers in antiquity sometimes dealt with themes common to modern science fiction, their stories made no attempt at scientific and technological plausibility, the feature that distinguishes science fiction from earlier speculative writings and other contemporary speculative genres such as fantasy and horror. The genre formally emerged in the West, where the social transformations wrought by the Industrial Revolution first led writers and intellectuals to extrapolate the future impact of technology. By the beginning of the 20th century, an array of standard science fiction “sets” had developed around certain themes, among them space travel, robots, alien beings, and time travel (see belowMajor science fiction themes). The customary “theatrics” of science fiction include prophetic warnings, utopian aspirations, elaborate scenarios for entirely imaginary worlds, titanic disasters, strange voyages, and political agitation of many extremist flavours, presented in the form of sermons, meditations, satires, allegories, and parodies—exhibiting every conceivable attitude toward the process of techno-social change, from cynical despair to cosmic bliss.

Science fiction writers often seek out new scientific and technical developments in order to prognosticate freely the techno-social changes that will shock the readers’ sense of cultural propriety and expand their consciousness. This approach was central to the work of H.G. Wells, a founder of the genre and likely its greatest writer. Wells was an ardent student of the 19th-century British scientist T.H. Huxley, whose vociferous championing of Charles Darwin’s theory of evolution earned him the epithet “Darwin’s Bulldog.” Wells’s literary career gives ample evidence of science fiction’s latent radicalism, its affinity for aggressive satire and utopian political agendas, as well as its dire predictions of technological destruction.

This dark dystopian side can be seen especially in the work of T.H. Huxley’s grandson, Aldous Huxley, who was a social satirist, an advocate of psychedelic drugs, and the author of a dystopian classic, Brave New World (1932). The sense of dread was also cultivated by H.P. Lovecraft, who invented the famous Necronomicon, an imaginary book of knowledge so ferocious that any scientist who dares to read it succumbs to madness. On a more personal level, the works of Philip K. Dick (often adapted for film) present metaphysicalconundrums about identity, humanity, and the nature of reality. Perhaps bleakest of all, the English philosopher Olaf Stapledon’s mind-stretching novels picture all of human history as a frail, passing bubble in the cold galactic stream of space and time.

Stapledon’s views were rather specialized for the typical science fiction reader. When the genre began to gel in the early 20th century, it was generally disreputable, particularly in the United States, where it first catered to a juvenile audience. Following World War II, science fiction spread throughout the world from its epicentre in the United States, spurred on by ever more staggering scientific feats, from the development of nuclear energy and atomic bombs to the advent of space travel, human visits to the Moon, and the real possibility of cloning human life.

Antecedents

Antecedents of science fiction can be found in the remote past. Among the earliest examples is the 2nd-century-ce Syrian-born Greek satirist Lucian, who in Trips to the Moon describes sailing to the Moon. Such flights of fancy, or fantastic tales, provided a popular format in which to satirize government, society, and religion while evading libel suits, censorship, and persecution. The clearest forerunner of the genre, however, was the 17th-century swashbuckler Cyrano de Bergerac, who wrote of a voyager to the Moon finding a utopian society of men free from war, disease, and hunger. (See belowUtopias and dystopias.) The voyager eats fruit from the biblical tree of knowledge and joins lunar society as a philosopher—that is, until he is expelled from the Moon for blasphemy. Following a short return to Earth, he travels to the Sun, where a society of birds puts him on trial for humanity’s crimes. In creating his diversion, Cyrano took it as his mission to make impossible things seem plausible. Although this and his other SF-like writings were published only posthumously and in various censored versions, Cyrano had a great influence on later satirists and social critics. Two works in particular—Jonathan Swift’s Gulliver’s Travels (1726) and Voltaire’s Micromégas (1752)—show Cyrano’s mark with their weird monsters, gross inversions of normalcy, and similar harsh satire.

Another precursor was Louis-Sébastien Mercier’s L’An deux mille quatre cent quarante (c. 1771; “The Year 2440”; Memoirs of the Year Two Thousand Five Hundred), a work of French political speculation set in a 25th-century utopian society that worships science. While many writers had depicted some future utopian “Kingdom of God” or a utopian society in some mythical land, this was the first work to postulate a utopian society on Earth in the realizable future. The book was swiftly banned by the French ancien régime, which recognized that Mercier’s fantasy about “the future” was a thin disguise for his subversive revolutionary sentiments. Despite this official sanction—or perhaps because of it—Mercier’s book became an international best seller. Both Thomas Jefferson and George Washington owned copies.

Science fiction is a special type of fiction, or story. Humans have long wondered what life on another planet might be like. People have also wondered how different kinds of technology might affect life on Earth. Made-up stories that address such questions are called science fiction.

On Oct. 30, 1938, the night before Halloween, Orson Welles performed a dramatization of H.G. Wells’s 1898 novel, The War of the Worlds, on his Mercury Theatre on the Air. Although it was announced at the beginning and middle of the radio program that the Martian invasion of New Jersey was only fiction, thousands of listeners panicked. They believed the "news bulletins" that reported a "monster" attack on the northeastern United States.
